Zero-Max's low inertia, lightweight coupling with high rotional stiffness for servo motor applications comes with its aluminum CD model in single and double flex versions.

The CD coupling has a robust though lightweight aluminum design. The working part is made of a composite material. The composite disc design handles the stresses of a servo motor's high acceleration rates and high torque capacity. The result is lower energy requirements, longer life of the motor and other operating components with uninterrupted system operation.

"We surveyed design engineers to find out what was the most desirable feature when specifying couplings for servo motor applications," says Robert Mainz, Zero-Max sales manager. "Low inertia was the most important. These engineers said they continually look for ways to reduce cycle time and improve system productivity. A lightweight yet high strength coupling design will enable the designer to increase the speed of the actuator. The combination of the lightweight aluminum hubs and unique composite disc provides the necessary characteristics to increase speed and cut cycle times. Lightweight couplings will also have an effect on the energy consumption in their designs. The aluminum CD couplings meet those objectives and more."

Applications include automated packaging systems and assembly machinery where precise, high speed positioning is required. The Zero-Max CD couplings are available in single and double flex models with or without keyways. The double-flex version is for precision applications requiring misalignment capacity greater than the single flex design. The single flex models have a torque capacity range from 40 Nm to 1,436 Nm and higher with speed ratings from 4,400 rpm to 17,000 rpm.
